  author={S. Microtechnique},
Abstract In this thesis, we present the development of a tunable Multi-HeterodyneScanning Near-Field Optical Microscope (MH-SNOM). This instrument has beenbuilt and evaluated for the investigation of optical near fields in amplitude, phaseand polarization. With this microscope, the response of a structure illuminatedwith two orthogonally polarized beams can be simultaneously measured both inamplitude and phase. Moreover, the integral state of polarization at the surfaceof a specimen can be… Expand
Phase-sensitive near field Investigation of Bloch surface wave propagation in curved waveguides
Bloch surface waves (BSWs) are electromagnetic surface waves excited in the band gap of a one dimensional dielectric photonic crystal. They are confined at the interface of two media. Due to the useExpand

Bloch surface waves in ultrathin waveguides: near-field investigation of mode polarization and propagation
In this work, we use a multi-heterodyne scanning near-field optical microscope to investigate the polarization and propagation of Bloch surface waves in an ultrathin (∼λ∕10) ridge waveguide. First,Expand
Heterodyne detection of guided waves using a scattering-type Scanning Near-Field Optical Microscope.
A technique of heterodyne detection allowing us to overcome this difficulty while amplifying the near field signal, and provides the local phase variation of the guided field in the case of a highly confined SOI structure. Expand
Microscopic theory of the extraordinary optical transmission
A microscopic theory of the transmission through subwavelength hole arrays is derived, by considering the elementary processes associated with scattering of surface-plasmon-polariton (SPP) modes by individual one-dimensional chains of subwa wavelength holes, and derives analytical expressions for all the transmission spectrum characteristics.

Measuring three-dimensional polarization with scanning optical probes
In optical fields with sub-wavelength features the longitudinal field components become considerable. Therefore, the paraxial concept of 2D polarization has to be replaced by the description of theExpand
Near-field analysis of surface waves launched at nanoslit apertures.
This work provides a direct observation of the near-field in a slit-doublet experiment at optical wavelengths and shows that two distinct waves are involved: a surface plasmon polariton and another wave with a free-space character. Expand
Exploring light propagating in photonic crystals with Fourier optics
Photonic crystals (PhCs) act on light in two different ways: confinement and modification of propagation. Both phenomena rely on the complex interplay between multiply scattered waves that can formExpand
Two-dimensional optics on silicon nitride multilayer: Refraction of Bloch surface waves
When properly designed, a dielectric multilayer can sustain Bloch surface waves (BSWs). Using a multiheterodyne scanning near-field optical microscope that resolves phase and polarization, we willExpand

Polarization effect in scanning near-field optic/atomic-force microscopy (SNOM/AFM)
Abstract The polarization effect is reported using a bent optical fiber probe for a scanning near-field optic/atomic-force microscope (SNOM/AFM). We have demonstrated that the SNOM/AFM could beExpand
